Shortwave Radiogram, 10 al 13 de Junio 2021: programa 208

This week, after months of planning, preparation, and purchases, three new amateur radio antennas were installed on my roof. They are 1) a 10 and 6 meter vertical, 21 feet (6.4 M) tall, 2) a homebrew 10 and 6 meter fan dipole (horizontal), and 3) a omnidirectional horizontal antenna for 2 meters. These join my three existing antennas: 1)  a vertical yagi with three elements each on 2 meter and 70 centimeters, 2) a 40-meter inverted V, and 3) a 160-meter “inverted U” wire antenna that currently tunes on all bands except 160. All six antennas are connected to my one overworked “shack-in-a-box” Yaesu FT897D transceiver.

On 10 meters, my WSPR signals have reached Brazil, French Guiana, Costa Rica, and Hawaii.  Not much has happened yet on 6 and 2 meters, except some local and regional FT8 contacts.

Anyway, moving on to the topic of this email: On this weekend’s Shortwave Radiogram, we will continue our demonstrations of MFSK in non-Latin alphabets. This time it will be Russian, consisting of a brief excerpt of a news story from VOA Russian. There will also be English news stories in MFSK32 and MFSK64, including ten MFSK64 images.  

A video of last weekend’s Shortwave Radiogram (program 207) is provided by Scott in Ontario (Friday 1300 UTC). The audio archive is maintained by Mark in the UK. Analysis is prepared by Roger in Germany.

Also this weekend, Daz Man writes: “I have some Ham-DRM data. Needed: EasyPal or WinDRM plus 7zip (Windows) QSSTV or TRXAMADRM plus p7zip (Linux) Data is Mode E, QAM4, 3 passes – also with 3dB PAPR processing to boost SNR.”

“This is a Music Show” Most of the show is a music show, but the host transmits some MFSK text and image near the end of the broadcast. It’s transmitted on WRMI, Thursdays at 0200-0300 UTC on 5850 kHz (Wednesday evening in the Americas) and a new time also on WRMI, Wednesdays at 2100-2200 UTC on 7780 kHz (aimed towards Europe) . Also look for a waterfall ID at the beginning of the show. . @ThisIsAMusicSho

New York and Pennsylvania NBEMS nets. Most weekends, as KD9XB, I check in to the New York NBEMS (Narrow Band Emergency Messaging Software) net Saturday at 1300 UTC on 3584 kHz USB, and the Pennsylvania NBEMS net Sunday at 1230 UTC on 3583 kHz USB (with out-of-state check-ins now starting at 1130 UTC). Check-ins are usually in Thor 22, and messages are in MFSK32. Messages generally use the Flmsg add-on to Fldigi. If you are a radio amateur in eastern North America, feel free to check in. Outside the region, use an SDR in the eastern USA to tune in and decode. You do not need Flmsg to check in, and most of the messages can be read without Flmsg. If you can decode the net, send me an email to , or tweet to @SWRadiogram, and I will let them know you are tuned in. USEast NBEMS Net: Please also note the USEast NBEMS Net, Thursdays 0000 UTC (Wednesdays 7 pm EST) on 3536 kHz USB.

Thanks for your reception reports!

Producer and Presenter

Shortwave Radiogram

Frank in Perth, Western Australia, received text and images 6 June 2021, 0800-0830 UTC, on 7730 kHz from WRMI Florida, about 18300 km. Frank used a restored 80-year-old BC455 military type radio. He received 100% text and all images, and had to turn down the RF gain control because of the very strong signal from WRMI ….
